It does, just what you see is not what your eye "sees" <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/smile.gif' class='bbc_emoticon' alt='
' />. I.e. brains correct and create final image, it is not "direct translation" from the eye. Existence of longitudinal CA's is used in optometry. There is a "red-green" test, that allows to check if the refraction of the eye was corrected well enough (hypermetropes better sees in green color, myopes - in the red one).

So we humans have a built-in CA correction then <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='
' />. That's indeed good... But why can we still see the CAs on image samples <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/tongue.gif' class='bbc_emoticon' alt='
' />...
By the way, I wish digital sensors could mimic the human eye one day... A concave image sensor... Would'n that be great <img src='http://forum.photozone.de/public/style_emoticons/<#EMO_DIR#>/biggrin.gif' class='bbc_emoticon' alt='' />...
